Embodiment 1

[0040] This embodiment illustrates the structure and structure of the geothermal water purification treatment device of the present invention.

[0041] like figure 1 As shown, the geothermal water purification treatment device of the present invention mainly consists of a manganese sand filter (3), an ultrafiltration membrane module (4), a boron removal resin module (6), and a first-stage reverse osmosis module (11); The connection sequence of the components is as follows: the manganese sand filter (3) is sequentially connected to the ultrafiltration membrane component (4), the boron removal resin component (6), and finally connected to the first-stage reverse osmosis component (11).

[0042] Wherein, the manganese sand filter (3) has its own backwashing device.

[0043] Further, the device also includes an intermediate water tank (7), a booster pump (8), a security filter (9), and a high-pressure pump (10), wherein the boron removal resin assembly (6) is connected to the int...

Embodiment 2

[0051] This embodiment illustrates the method of utilizing the geothermal water purification treatment device of the present invention to process geothermal water, such as figure 1 As shown, it mainly includes the following steps.

[0052] 1) The geothermal water in the geothermal well (1) is directly connected to the manganese sand filter (3) through the feed pump (2) to remove most of the iron, manganese oxides and solid suspended matter in the water to ensure the smoothness of the subsequent process. Running stability.

[0053] 2) The geothermal water flowing out of the manganese sand filter (3) is filtered through the ultrafiltration membrane module (4), and the high molecular organic matter, fungi, suspended particles, pyrogens and various types of silicon, iron and aluminum in the water are retained. Impurities such as colloids; concentrated water intercepted by ultrafiltration is discharged.

[0054] Wherein, the filtration method of the ultrafiltration membrane modul...

Embodiment 3

[0062] The 90°C geothermally produced water is pressed by 1.6 m 3 / h flow into the geothermal water purification system, the water quality before and after geothermal water purification is shown in Table 1.

[0063] The geothermal water first enters the manganese sand filter, and uses the oxidation method to oxidize the low-priced iron ions and low-priced manganese ions in the water into high-valent iron ions and high-valent manganese ions, which are then removed by adsorption and filtration. The upper layer of the filter is anthracite, the middle layer is natural manganese sand, and the bottom layer is magnetite. The design flow rate is 5m / h. When the pressure difference between the inlet and outlet water reaches 0.1Mpa, backwashing is performed, and the water backwashing intensity is 1.5 m 3 / min·m 2 , the gas backwash intensity is 5.0 m 3 / min·m 2 , backwashing lasted 10min.

[0064] The ultrafiltration membrane system uses a tubular inorganic ceramic membrane with a p...

Description

technical field [0001] The invention relates to a geothermal water purification treatment device and a method for processing geothermal water, belonging to the technical field of water treatment. Background technique [0002] Geothermal water is a precious natural resource. It can not only provide non-polluting heat energy to human beings, but also can be exploited and utilized as water supply source or mineral resources, which is of great significance to the development of national economy. Geothermal water resources have various and increasingly widespread uses. The prior art uses geothermal water mainly for the following two aspects: [0003] (1) Using geothermal power to generate electricity [0004] The main countries in the world that use geothermal power generation are Italy, New Zealand, Mexico, the United States, Indonesia, Turkey, the former Soviet Union, El Salvador, Kenya, Iceland and Japan. After our country built the first experimental thermal power station ...
